25ml Glass Density Bottle, Calibrated

This 25 ml density bottle according to Gay-Lussac, Class A, is an essential tool for measuring the density or specific gravity of liquids using gravimetric methods under controlled temperature conditions. Constructed from durable borosilicate 3.3 glass, it provides exceptional chemical resistance and robustness. Calibrated at 20 ?C, its precise capacity is clearly marked on the surface after adjustment with distilled water. The ground glass stopper ensures an airtight seal for accurate measurements and prevents leakage. With a measurement tolerance of ? 2 ml, it adheres to ASTM 438 and DIN 3507 standards, guaranteeing high reliability and quality. Widely used in scientific research, it delivers precise and consistent results for liquid and gas density analysis.
